Conversion formula

The conversion factor from knots to miles per hour is 1.1507794480225, which means that 1 knot is equal to 1.1507794480225 miles per hour:

1 kt = 1.1507794480225 mph

To convert 3 knots into miles per hour we have to multiply 3 by the conversion factor in order to get the velocity amount from knots to miles per hour. We can also form a simple proportion to calculate the result:

1 kt → 1.1507794480225 mph

3 kt → V_(mph)

Solve the above proportion to obtain the velocity V in miles per hour:

V_(mph) = 3 kt × 1.1507794480225 mph

V_(mph) = 3.4523383440676 mph

The final result is:

3 kt → 3.4523383440676 mph

We conclude that 3 knots is equivalent to 3.4523383440676 miles per hour:

3 knots = 3.4523383440676 miles per hour
